Import graph and read data

As the title says, I need some help with importing and using a graph in Unity. I have it as png/pdf but I can probably convert it to something else if needed. What I wanna do is import the graph in Unity, and be able to read information from it. For example, I wont show all of the graph, I will show only the beginning of it, and over 10 seconds I am moving the camera to the right, so it shows more and more of it, and if the graph is going up, the player is earning points, if it goes down, the player loses points. Any idea how to achieve this ? I really don't know how to google this or what to read to implement what I want. Thanks a lot.
